Back plate Assembly
S2912 follows AMD 1U/2S CPU keep out zoon spec, please use 1U RevF back
plate on S2912, the distance of two mounting hole use to lock the CPU heatsink
is 4.1 inch. The back plate is mounted on the backside of the motherboard and
enhances local stiffness to support shock and vibration loads acting on the heat
sink. The back plate assembly prevents excessive motherboard stress in the
area near the processor. Without a back plate, excessive stress could cause
serious damage to electrical connections of the processor socket and integrated
circuit packages surrounding the processor. The back plate also serves as a
reinforcement plate for the LGA socket.
While doing the installation, be careful in holding the components. Follow these
instructions to install your back plate:
1. Remove the release liner from the back plate.
2. Align the PEM nuts on the back plate to the holes on the reverse side
of the PCB.
3. First, insert the taller upper & lower middle PEM nuts through the
holes of the PCB. The remaining four shorter PEM nuts should
automatically fit the 4 holes on the PCB as shown in the following
pictures.
Let 2 upper &
lower-middle PEM
nuts pass
through the
holes.
4 PEM nuts
should fit 4 holes.
